Georgia spring notes: Carter, the secondary and Marshall

Carter came to Georgia last year as a five-star outside linebacker who had just 7 percent body fat. Now he's up to 11 percent, with a goal of 15 percent.

Which begs the question: Why?

"That's the typical body fat percentage (for) the NFL outside linebackers," Carter said Thursday. "That's what we try to do, look at the body fat percentages for every position in the NFL and try to get it up there to that range."

Carter said he has also gained about 20 pounds since he enrolled, and is now around 242 pounds. There was a play last year when Carter went from one sideline to another to make a tackle from behind. The extra weight doesn't prevent him from making such plays, he said.

"Actually (while) I'm putting on the pounds making sure I'm not too heavy so I can run, keep the speed up. I feel faster than ever right now," Carter said.

Defensive back tidbits

Jarvis Wilson, the freshman early enrollee, continues to get positive mention from veterans this spring. The latest to name-check Wilson was safety Quincy Mauger, a rising junior who was the only defensive back made available to the media on Thursday.

"He has a good head on his shoulders, and he's working real hard," Mauger said of Wilson. "I can see why they like him."

Mauger also offered some updates on several other defensive backs, who each continue to work their way back from injuries.

Shattle Fenteng, whose shoulder problems caused him to take a medical redshirt last season, is "getting back in the flow," according to Mauger.

"I know he's hitting again, so that's a good sign," Mauger said.

Tramel Terry, who will be entering his third year at Georgia, has yet to play much because of the lingering effects of the ACL tear he suffered in December of 2012. Terry has been playing both cornerback and safety.

"He gives great effort, every play, every snap," Mauger said. "He's still learning. He's still coming off that leg injury, so it's nice to see that he doesn't make any excuses on his leg. He progresses every day, one play at a time."

Keith Marshall update

Tailback Keith Marshall left Georgia's practice on Thursday, which was attended by more than a hundred high school coaches as part of the annual UGA coaches' clinic. Marshall returned with ice on his leg, according to those who were there.

UGA hasn't announced anything, but a source said Marshall only has a hamstring injury. It's uncertain how much time he would miss.
